In a video message recorded for fans, Flynn says: "I have been battling a chest infection or a chest flu for a few days now. I can't stop coughing and I have basically blown my voice out onstage. It started happening yesterday, but there's nothing coming out of my throat right now. I am so, so sorry that we had to stop but I hope you understand."

The next date on the band's European tour is scheduled for Luxembourg's Den Atelier on February 17 (Wednesday) and they say they'll have to "wait and see" how Flynn's illness is before they know whether it'll go ahead.
